Domain is the most inclusive of the three, genus is the least inclusive
Prey or predation is a biological interaction where a predator (an organism, often an animal) kills and eats its prey (another organism).
Like a mouse getting caught and eaten by a bird of prey (Eagles, hawks, etc.)
Answer:
D. stabilizes the position of the kidneys by holding them in their normal position
Explanation:
Adipose tissue is a type of connective tissue and is therefore called by some adipose connective tissue. As we saw in the article “Connective Tissue Cells”, adipose tissue is made up of adipose cells, also called adipocytes. Fat tissue specializes in fat storage and is found well below the skin.
Some of our internal organs like kidneys and heart have a layer of adipose tissue lining them. This layer of fat around the organs gives them greater protection against mechanical shock. In addition, in the kidneys, adipose tissue fills the voids between other tissues and helps keep these organs in their normal positions.
Answer:
Glucose entering the intestines from the villus.This is by active transport.The latter is defined as the movement of molecules and solutes from the region of lower concentration to the region of higher concentration against the concentration gradient.
Explanation:
All the above options depends on the diffusion gradients from one higher region to another.e.g oxygen passing from high concentration from outside to lower concentration in blood stream,like wise Co2 from higher concentration from inside to outside,with passive diffusion lipids and water enter the small intestine(note amino acid and glucose,and fructose are different).
Active transport( through sodium dependent transporter) transports glucose to the intestine from the villus.This is movements against concentration gradient because,glucose molecule are concentrated in intestine,and needed by the cells, in the body.Therefore they must be transported as a fast rate inn the blood .
However the absorption by the villi is very slow,therefore active transport is needed to move these against the concentration gradient into the intestine.And finally the blood.
If this were to be moved by passive diffusion,the high concentration in the intestine will force this back into the villi
Therefore extra energy is needed by active transport for the glucose molecules to enter the intestine from the villus.
